Description
The validator flags all closed, clockwise coastlines as "Reversed coastline: land not on left side". This incorrectly assumes that every closed coastline must be an island.
While it might not be best practice it is not an error to tag pieces of water in this way. In fact, there are many PGS coastlines that are like that. However, I agree that those coastlines should be fixed.
I would propose to downgrade the error to a warning and call it "Clockwise coastline" or similar. Without an extensive analysis of the surrounding coastlines it is difficult for the validator to decide whether it is an island that should be reversed or water that should be tagged natural=water or so.

Replying to mjulius:
No, closed coastlines must be islands. If a body of water is mapped as a closed way, it should not be tagged as natural=coastline, but as natural=water
Yes, it is an error, the coastline error checker http://wiki.openstreetmap.org/wiki/Coastline_error_checker will mark them as errors.
It's definitely an error and shouldn't be downgraded to a warning. The wording however could be changed, but is there enough room or some other way to include tips that it probably should be tagged as natural=water if it's lake etc.?
